High Frequency Hybrid PCB 4 Layer Mixed PCB Board Bulit On Rogers 12mil RO4003C and FR-4
(PCB’s are custom-made products, the picture and parameters shown
are just for reference)
Hi Everyone,
Today, we’re going to talk about 4-layer high frequency PCB made on
12mil RO4003C and FR-4 combined.
The board is designed as a 4-layer structure, because 4-layer PCB
is relatively simple and inexpensive, which is helpful to open up a
new market.
Let’s see today’s first board.
Viewing from stack up, we can see the 1st layer to the 2nd layer
and 4th layer to 3rd layer are 12mil core of RO4003C, the core has
fixed thickness which is very important to the electrical length of
RF lines on the circuit board, and the rest are FR-4 materials.
Copper weight on inner layer and outer layer is 1 ounce.
The 2nd board FR-4 is moved to layer 3 and layer 4. According to the
actual applications, the thickness of dielectric material and FR-4
can be adjusted.
The applications of 12mil RO4003C hybrid PCB is wide, such as
Modular oscilloscope, antenna combiner, balanced amplifier, 4G
antenna etc.
The advantages of 12mil RO4003C hybrid PCB are reflected in
following 3 points:
1) RO4003C exhibits a stable dielectric constant over a broad
frequency range. This makes it an ideal substrate for broadband
applications.
2) Reducing signal loss in high frequency application meets the
development needs of communication technology.
3) Cost reduced over stack-ups with all low loss material;
At present, the mature mixed pressing materials are as follows:
RO4350B + FR4;
RO4003C + FR4;
F4B + FR4;
RT/duroid 5880 + RO4350B
RT/duroid 5880 + FR4
